Jeffrey Donenfeld

Wrist Watch Review Writer Jeffrey Donenfeld lives in Colorado and reviews products at his website. An accomplished adventure traveler, antarctic expedition director, and rescue scuba diver, Jeffrey has tested and reviewed watches in a multitude of challenging environments.
Jeffrey loves exploring design, construction, materials, and utility aspects of horology, and gets a kick out of both classics as well as fresh new ideas. He typically tests extensively watches he writes about, and provides readers with a real-world, practical take on diverse timepieces.
In addition to writing about time, Jeffrey also works as a venture capital investment manager at a growing startup accelerator in Boulder, Colorado. In his free time he travels (70+ countries and counting), snowboards, rock climbs, runs, sails, scuba dives, and occasionally relaxes.
